At the moment, postgrey kicks in at line 4. Are you suggesting we
(somehow) reconfigure postgrey to start later in the conversation,
say around line 6 or 8?<br>
<br>
I've spent the last several months trying various modifications on
"how to make greylist apply to the receiving domain and not the
sender domain", and have not been able to find a way to make
greylisting, a sender deferring technology, function at a
per-recipient domain level. <br>
<br>
Short of writing our own version of the SMTP standard, we're just
plain stumped on how we can make this happen. Can you perhaps share
a link to a page with instructions on how to make postgrey wait
longer in the conversation, and to defer at the recipient domain
level, rather than at the first identifying stage of the SMTP
transaction like it currently does?<br>
<br>
Or, alternatively, are you suggesting that LA runs multiple mail
servers for each type of service we currently consolidate down to
one machine, such as lists, general mail, RT instances, conferences,
etc, and only configure greylisting on the instances that really
critically need it?<br>
